对比英美电影字幕描述差异，揭示文化与规范影响叙事风格
Comparing British and American Audio Description of Movies
- 基于206部电影的英美人工配音数据，对比区域差异
- 发现英美在词汇、时态、被动语态、主观形容词等10项上存在显著不同
- 适合无障碍设计、跨文化研究及语音生成领域参考
为盲人和视障人士描述电影画面内容称为音频解说。该技术需在对话间隙中插入信息，并遵守各地规范，因此限制远超普通叙事。本文对比英国与美国的音频解说，结合两地指南及从业者意见提出假设，并利用包含206部影片的现有语料库进行验证。结果提供量化证据支持所有假设，包括词汇选择、进行时态使用、被动结构、主观形容词、角色命名时机、场景提示方式，以及与对白和音乐的重叠程度等方面的差异。研究为音频解说这一叙事技术提供了量化视角。
原文摘要 · Abstract (English)
Narrating the visual component of movies is known as audio description. It is a narrative technique designed to enable blind and visually impaired individuals to follow the story. However, it is far more constrained than most narratives: the descriptions not only need to convey the story in the movie, but they must also fit into gaps between dialogue and they need to conform to guidelines that exist in each region. In this work, we compare audio description created in the United Kingdom against audio description created in the United States. We use guidelines written for these two regions, alongside the impressions from a practitioner in the field, to motivate specific hypotheses about the differences. We test these hypotheses against our pre-existing corpus, which provides both human-authored American and British audio description for each of 206 movies. Results provide quantitative evidence to uphold all tested hypotheses, including differences in lexicon, the use of the progressive aspect, the use of passive constructions, the use of subjective adjectives and modifiers, when characters are named, how scenes are cued, and degree of overlap with movie dialogue and music. Our work offers a quantitative lens into the narrative technique of audio description.
